Motion with a constant speed - St. Thomas the Apostle School
... • Changing speed: intervals of speeding up and slowing down. For example-A car at a stop sign. • Average speed- The total distance traveled divided by the total time of travel. • Instantaneous speed- the speed at a given point in time • Changing instantaneous speed- the speed is different at every p ...

... Calculate the charge density and current as seen by an observer in S' moving with a speed v along the z axis. Calculate the electric and magnetic fields seen by this observer. Transform these fields to find the fields in the original frame. Check that these agree with a direct calculation in the ori ...

special relativity via electro-magnetic clocks
... Does time dilation effect other types of clocks? Another type of clock commonly considered in special relativity is the simple rod-clock, as described above. If this clock is at rest in a fundamental reference frame in which the speed of light is a constant c in all directions then its time unit is ...
